"Am I so terrible?" grabbed Liu Yu by the collar and walked out of the study, Liang Yu asked angrily.

"Where, my sister is the most beautiful and gentle, no one can compare to you!" Listening to the laughter of the three old men in the study, Liu Yu called a regret! You already know the feelings, and you don't say a word to me, the most annoying thing is Zhang Tianqi's kid, who slipped faster than a rabbit. Forget it if you slipped away by yourself, and pulled Zhou Sheng away, didn't this let me face this tigress alone?

"It's nice to say, are you cursing me as a tigress in your heart?" Liang Yu mercilessly dragged Liu Yu into the gazebo in the garden, and then let go of his hand.

"How dare I!" Liu Yu, who was guessed about his thoughts, tried his best to cover up. But I was thinking in my heart, women are sensitive, and this little bit of thought can be guessed, and they won't let me live in the future.

"Let me ask you, why didn't you say a word to me when you entered the beast clan this time? It's been a few months, do you know how worried people are about you!" Seeing that Liu Yu no longer wanted to slip away, Liang Yu sat down in the pavilion and said with red eyes.

"I'm not afraid that you'll be worried, although I'm very confident in myself, but I'm afraid of what if! So I didn't dare to tell you, isn't it good to come back now, and you shouldn't be sad. Looking at Liang Yu's red eyes, Liu Yu's heart trembled for no reason, and he hurriedly comforted.

"Do you know how I've been here in the months you've been away, worrying every day, even if I get news of your misfortune one day, or if I'll never see you again. I pray for you every day that you will come back safely. But it's good that you only care about your own merry, I'm afraid you have forgotten me a long time ago!"

"You don't know that when we were in the orc territory, we were also scared, for fear that one of us would accidentally expose a flaw and fall inside. You've heard what you said today, we didn't travel there, we did so many things, and burned a lot of strategic materials stored by the beasts. ”

"There are only three of you, how can you destroy so many warehouses, was the situation dangerous?" Liang Yu asked worriedly and curiously.

"There are definitely dangers, but with my careful planning and reasonable planning, the dangers are naturally minimized. Liu Yu said proudly, "I'm a top student of the Bokan Military Academy, and it's not easy to deal with those stupid beasts." ”

"You can blow it, and you are not afraid to blow the cowhide out!" Liang Yu sneered.

"I'll show you what I'm doing later. Liu Yu feigned anger.

"Alright, I know you're very good!"

"How have you been doing in the past few months since we left, and have you encountered anything unhappy?"

"As long as you don't make me angry, don't be too comfortable. ”

"I think I'd better get out of here quickly, or I'll be upsetting you again. Liu Yu said seriously, turned around and prepared to leave.

Liang Yu slapped Liu Yu twice hatefully: "Are you begging to beat again?"

Quickly grabbed the powder fist that Liang Yu pounded on his body, and pulled her into his arms, Liu Yu whispered in her ear: "Sister Liang Yu, after being away for so long, I miss you all the time, and when I am not together, I know how happy it is for two people to get along!"

Leaning on Liu Yu's body, between the ears and temples, the two of them had endless words to confide in each other, and they didn't leave Guan Xing's mansion together until the dead of night.

The next day, after successfully registering, Liu Yu started the study of the new school year. After some experience in the territory of the beast clan, the three of them have discovered some of their own shortcomings, so they also work harder and are more targeted when they study.

Before you know it, a month has passed. Not only is he busy studying, but he also has to go to Bokan Equipment Group from time to time to take a look, Liu Yu almost has no idle time.

Liang Yu is also busy with her work at the Bokan School of Engineering, after all, it is the first time to take over the position of dean, and she has to deal with big and small things. During the holidays, she had already started to prepare for the new school year, and when the school started, all the work was finally on the right track.

Therefore, there is not a lot of time for two people to meet. Even if we meet once in a while, we are more likely to discuss the future development of Bokan Equipment Group and the research of scientific and technological level.

In the production and construction of Bokan Equipment Group, the construction of railways and bridges is a top priority. The so-called soldiers and horses have not moved, and the grain and grass go first. After all, if the transportation capacity is not reached, no matter how much equipment is produced, it will not be able to be transported to the front line.

Four major railway lines have been built in the Dragon Empire for interconnection between the fortress and the inland city. More than 200 locomotives now fly on the four railways every day, transporting supplies and personnel to the fortress.

The waterways used for shipping have also been widened and deepened. The steamships used today carry ten times more cargo than the wooden sailboats of the past, and the corresponding steamers are larger and have a deeper draft.

The fall of Tower Hill Fortress also greatly increased the demand for gunpowder. In the absence of more and better weapons and equipment at this stage, the use of gunpowder can be a fast and effective means. Over the past few months, Liangshan has developed several gunpowder weapons and equipped them with various fortresses.

There are three main types of such weapons, one is to pour gunpowder into the stones, and throw them out with a catapult after ignition, which increases the power of the explosion than the stones thrown out before, although it is only a simple use of gunpowder, but the effect is still very good, at least the shock wave generated by the explosion and the lethality of the blast gravel are still quite large. The larger the stone block and the more gunpowder it is loaded, the better the effect. This weapon was named Fire Thunder by Yangsan.

The second is to fill the bamboo tube with gunpowder and gravel, and then tie the bamboo tube to the crossbow arrow, and use the crossbow to shoot the arrow after igniting it. The bamboo tube for the light crossbow is a little smaller, and the thickest bamboo tube is used for the heavy ballista, and there is more than one. Yangsan called the crossbow bolt attached to the bamboo tube a rocket.

The third is the idea of Liang Shan, using the special surname of gunpowder flammability, Liang Shan designed an automatic ignition device. This device will explode when it is under the weight of an external force, and if it is placed in the gunpowder, it can play the role of automatically detonating the gunpowder under the action of external force.

Originally, Liang Shan was also going to apply this device to catapults and crossbow arrows, but it was difficult to hit the ignition device when the stones and crossbow arrows landed, so he could only retreat to the next best thing and chose to ignite the fuse directly. This problem has to be left for later and slowly solved.

Liang Shan named this weapon that could detonate automatically, and buried it in the open field outside the fortress and on the orc attack route, and it would be detonated as soon as the orc soldiers stepped on it. The downside is that it can't move to attack, it can only defend passively, and if the orc doesn't step on it, it won't explode. And if the enemy has time to clean it up, it can be cleared from the ground.

Of course, if the orcs did this, their attack would be much slower, after all, it was buried in the ground, and it needed to be searched slowly, and it took a lot of time to clean up a large area. And the human defenders in the fortress won't let them clean it up slowly.

With the addition of these weapons, the human defense was much more solid, and now there were large minefields outside each fortress, leaving only a few small passages to enter and exit the fortress. Soldiers and civilians alike were also forbidden to move outside the fort at will, after all, landmines were indefinite and would explode if anyone stepped on them.

Steam locomotives and steamships have also advanced to the second generation, and the steam engine has become smaller and has gained much more power than the first generation. At present, the delivery of supplies to the various fortresses is basically carried out by these two means of transportation.

With steam locomotives and steamships, the speed and quantity of cargo transportation have not only been greatly improved, but also a lot of manpower and animal power have been saved. Since then, the way humans transport has been completely changed.

Compared with steam locomotives, steamships are much slower, but the cargo throughput of steamships is not comparable to that of steam locomotives. Therefore, some large-scale goods that are not very time-critical are transported by ship.

A large number of strategic resources were continuously transported into the fortress, ready for a possible attack by the orcs. Each fortress now has enough equipment for a million soldiers to last for half a year. Among them, the largest number of gunpowder weapons are specially opened up in warehouses for storage, and fireworks are strictly prohibited around the warehouses to avoid igniting gunpowder, which will cause great losses.

In the meantime, Liu Yu and Man Yi learned about the operation of the Heavenly Trade Union through a conversation. With the full support of Prince Yude, the development of the Heavenly Union can be said to be smooth sailing, and it is now busy completing the tasks assigned by His Royal Highness. To produce one million sets of equipment in half a year, the time is still very tight, but since it is the request of His Royal Highness, no matter how difficult it is, it must be done well.

With sufficient funds and materials, the number of engraving technicians is gradually increasing, so the production rate of equipment is also increasing step by step. A total of 80,000 kits were produced in the first month, increasing to 120,000 in the second month. According to Manyi's calculations, according to the current growth rate, it should be able to complete the task ahead of schedule.

The equipment produced will be used to equip the orc soldiers of Prince Yude's faction. As for the next attack target of these orc soldiers, Man Yi has not yet inquired clearly, and can only make a preliminary judgment based on the orc legion that first replaced the new equipment and the location of their garrison.

Liu Yu attached great importance to this, and asked Man Yi in detail about the station, number, number, composition of troops, the name and resume of the commander of the regiment, and the combat effectiveness of the first batch of orcs that replaced the new equipment.
